SAN DIEGO (CNS) - Detectives Monday were hunting for the knife-wielding suspect who stabbed another man several times in the head and face during an argument in Hillcrest, police said.

The 51-year-old victim survived the attack, which happened around 7:10 p.m. Sunday, but was hospitalized with serious, life-threatening injuries, San Diego police Officer John Buttle said. A man who was detained shortly after the stabbing was later released after police determined he was not involved in the attack.

The violence was first reported after the wounded victim walked to the corner of Richmond Street and University Avenue, Buttle said. That's where police made contact with him and where paramedics first treated him before taking him to a hospital.

Officers later learned the victim's injuries were sustained near a residential intersection two blocks away at Richmond and Essex streets, Buttle said. The victim walked north after the attack toward the bustling University Avenue intersection, while the suspect was last seen running west in the 1300 block of Essex Street.

Witnesses described the suspect as a roughly 5-foot-6-inch to 5-foot-8- inch man under 40. He was last seen wearing a black and gray pullover top, gray sweatpants and Nike running shoes.
